Standard Fin KOI

Standard Fin Koi (Cyprinus carpio), a popular variety of koi fish, are known for their distinctive long fins and vibrant colors. These ornamental fish are a result of centuries of selective breeding, originating from Japan, where they were initially cultivated for food. Today, they are primarily kept for decorative purposes in ponds and water gardens.

The physical characteristics of Standard Fin Koi include a robust body, elongated fins, and a wide range of color patterns. Common colors include white, orange, black, blue, red and yellow, often combined in intricate patterns. The size of Standard Fin Koi can vary significantly, with many reaching lengths of 12 to 36 inches, depending on their environment and care.
